Answer 1

you can plug in the first numbers and test it out to see whats closest

Answer 2

36-8 aint negative so it has real solutions

Answer 3

.4+5.6 = 6/2 = 3 ; and 6/2 = 3 but thats might be a lucky shot

.5+4.8 = 5.3/2 is less than 3 hmmm

and 1.2 + 2.4 aint got 3 inbetween them.

your axis of symmetry is 3 so id go a

Answer 4
